SPRING AIR-GUN.

SPECIFICATION forming part of Letters Patent No.454,081, dated June 16, 1891. Application filed June 25, 1890. Serial No. 356,631- (No model.)

.To all whom it may concern.-

Be it known that I, MERRITT F. STANLY, a citizen of the United States, residing at- Northville, in the county of WVayne and State of Michigan, have invented certain new and useful Improvements in Spring Air-Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in spring air-guns; and the invention consists in the peculiar construction, arrangement, and combination of the different parts, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure 1 is a vertical central longitudinal section through my improved gun. Fig. 2 is a cross-section thereof on line w 00. Fig. 8 is a cross-section thereof on line 3 3 Fig. 4 is a perspective View of the springabutment, showing the barrel, &c., in dotted lines.

A is the stock.

B is the fore-arm.

C is the false barrel, in the forward end of which is secured the true barrelD.

The stock is hinged to the fore-arm by means of the pin E, which passes through the extensions E of the trigger-guard F. The fore-arm is secured to the false barrel by means ofthe lug a, formed integrally with the barrel or soldered thereon, and the pin Z), lug and the fore-arm, and by means of the screw 0, which passes through the fore-arm and enters the triggersupporting block d, which is formed integrally with the barrel or is soldered thereon. This block has suitable lugs e, in which the trigger is pivoted. The trigger has the forwardly-projecting arm f, to the free end of which is pivoted the detent g, which projects through a suitable aperture into the false barrel. A spring h holds this normally projected into the barrel. The stock has the inclined face 2' and the vertical face j.

k is a cap having the rearwardly-extending flange l, by means of which the cap is secured to the stock. The upper edge of this cap forms a locking-flange, over which engages This latch is secured to the top of the false barrel at its forward end and has the upturned end n, forming the hind sight. The cap 7.; covers the rear of the false barrel.

0 is a thumb-piece on the latch m, by means of which it is disengaged from the cap 7s.

lVithin the false barrel is secured the abutment G for the spring H, which is sleeved over the rod I, upon the forward end of which is secured the piston I. A washer J is interposed between the spring and the abutment G. This abutment I form of wire, bent to form the bearing or head 2), the parallel guide-arms p, and the securing-pins g, which latter engage in suitable apertures in the false barrel, one on each side thereof. The rod I passes through an aperture in the washer and has secured to its rear end the cross-head K, which is guided within the false barrel and has notches L, which the arms 1) of the abutment engage.

M is a connecting-bar slidingly engaging through the aperture N in the cross head, and having a suitable head 0 formed at its forward end and connected to the cap 7; at its other end.

The spring is compressed by breaking down the stock which forms the retracting-lever upon its hinge, drawing back the piston I until the incline P upon the cross-head strikes the detent g, depressing it until it has passed, when the spring it throws it up again and locks the spring in its compressed position.

To load, a shot is dropped into the barrel, in the lower'end of which it is stopped and held by the spring Q.

R is a flaring or bell-shaped mouth in the rear of the true barrel in the rear of the spring, which materially assists in bringing the force of the compressed air upon the projectile.

That I claim as my invention is- 1. In a spring air-gun, the combination,with the barrel and spring-actuated piston, of the abutment G, formed with the head 1), guidearms 19, and securing-pins g, engaging in the apertures in the barrel, substantially as described.

2. In a spring air-gun, the combination,w1th the barrel and spring-actuated piston, of the abutment G, the cross-head K, connected to the piston and guided within the barrel, and

the barrel, of a stock hinged to the same, a locking-spring formed of a single piece of metal permanently secured on the barrel near the stock and extending beyond the end of the barrel over the stock, its rear end being bent to form a catch and thumb-piece and its forward end bent up toform a sight, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
